The main reason I wrote this email is plain and simple
curiosity about whether it can be done, and how: namely to feed sound
on a Linux machine to two audio systems at the same time: to
internal speakers on the computer and to external ones like, e.g.,
those in a TV, via HDMI. And all this on Fedora 26 system

but uses other higher level tools to accomplish what you're looking for,
specifically: pavucontrol (pulseaudio volume control) and paprefs
(pulseaudio preferences).
